LOCK'.

SPECIFICATION forming part of Letters Patent No..453,192, dated June 2, 1891.

V Application led January 14, 1891. Serial No. 377,704-r (Model.)

To a/ZZ whom t may concern.-

Beit known that I, CHARLES E. JONES, Sr., a citizen of the United States, residing at Florence, in the county' of Lauderdale and State of Alabama, have invented certain new and useful Improvements in Locks and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The special object of the invention is to .I

make a lock adapted to be conveniently used on the doors of tills, drawers, cupboards, closets, or wardrobes, the locking and unlocking being done by the knob-spindle, which may also be used as a drawerpull,while the locking may be done without the key, so as not to be preceptible to a-looker on.

Figure ,l of i the drawings is an elevation showing the inside of the lock; Fig. 2, a detail view of spindle with its attachments; Fig. 3, a similar view of the key and cylinder apart; Fig. 4, a similar view of theffence-plate; Fig. 5, a similar View of the locking-bolt, and Fig. 6 is a plan View of that part or plate of lock-case through Which the cylinder is entered.

In the drawings, A represents the lock-case, made intwo parts. a a', separately connected by two screws a2 a2, which work through part a into raised nuts 0,3 a3 on the part a. In a hole a4 and upper groove a5 is loosely secured a cylinder B, which has the slot b, and is made of greater diam eter at h than at b2. Through the upper groove a5 of case and the slot h of cylinder when registering with each other' is entered the key C, having the side studs c c c2 of differing heights for raising the tumblers D, which have end-open slots d, correspondingly different in height. By this relative construction all the tumblers may be raised at once to make all the slots register with each other and at th-e same time be in line with the fence e, which is arranged on a sliding plate E. The tumblers D are all pivoted on the same stud F and held down out of a horizontal position by a spring f,'which bears on the vertical pin f of the case. Next to these tumblers I arrange the plate E, containing the fence e on one side and the stud e on the other. This stud moves in a slot g of the lock-bolt G when the fence-plate is caused to slide, while the plateE has a slot c2 to guide it as it slides on the case-stud F. The bolt G is held forward by aspring g', and its shank G is supported by a case-flange g2. The plate E has a tooth c3, in which works a pawl c4, pivot-ed to case and pressed down by aspring e5, which rests with its rear end against the pin e6 of the case. This pawl c4 serves to hold the plate fast when it has been retracted, and thus to allow the bolt also to be retracted. In this position the fence e rests in the slots of all the tumblers.

H- is a cylinder, havinga square hole to receive the squared part 7- of the spindle K, which spindle has the knob 7c', shoulder 7.32, against which is supported the face-plate 7c3, and the slotted sliding sleeve 7a4. This sleeve is held at different points on the squared portion of the spindle to suit different thicknesses of door.

On the cylinder His a lug h, which goes under the plate E and raises the pawl e4 whenever the spindle K is turned to the right, and when the spindle is then turned farther another stud h presses ashoulder c7 of the plate E, so as to move it forward and carry the fence e outof the tumbler-slots, when the bolt is thrown forward by its spring. The fenceplate is now pressed in front against the shoulderwzl of the b'olt Gand locked in that position by the tumblers which have been thrown down in front by their rear spring. To retract the bolt it is necessary to raise the tumblers with the key and throw back the fence-plate E with the spindle-stud h. Then the spindlestud h will press the shoulder g of the bolt and retract it. Vhen the plate E is run back, the pawl c4 springs behind the tooth thereof and locks it back. The key C not only raises the tumblers by the studs c c c2, but immediately afterward slides back the plate E by means of a projection c3, which fits a corresponding recess e8 in the slide. Thus it will be perceived that the plate E may be slid back either by the key o r the knob-spindle; but the tumblers can only be lifted by the key, While the plate E can only be unlocked fl'om the pawl by the spindle. Hence the works the pa,\v1e*,pivoted on the caso, and Io door cannot belocked without using the spinthe spring-boli; G, having the slot g, as and dlo or unlocked Without using the key. for the purpose set forth.

NVhat I claim as new is- In testimony whereof I afiix my signature in 5 The spring-pawl e4, pivoted to oase, and the presence of two Witnesses.
